Enum LivenessSource 

pub enum LivenessSource {
    Pid,
    Listing,
}

Which source of liveness is authoritative for a session (DESIGN.md §8), recorded by the code that spawned the process because only it knows what it spawned. The two differ in one respect: whether the pid the session row holds is the work itself or a launcher that spawned it and exited.

Variants

Pid

The recorded pid is the work — a foreground child Voro owns, or an agent with no sessions verb, where the spawned pid is the only source there is. kill -0 answers.

Listing

The work belongs to a supervisor the launch handed it to, so the recorded pid dies at birth and only the agent’s own sessions listing can say whether the session is still working.
